A new ductility exhaustion model for high temperature low cycle fatigue life prediction of turbine disk alloys
Download2011
Zhu, Shun-Peng, Sun, Rui, Zuo, Ming J., Li, Haiqing, Huang, Hong-Zhong
Based on ductility exhaustion theory and the generalized energy-based damage parameter, a new viscosity-based life prediction model is introduced to account for the mean strain/stress effects in the low cycle fatigue regime. The loading waveform parameters and cyclic hardening effects are also...

Schweger, C.E., McKown, A.D., Stockey, R.A.
Three structurally preserved conifer ovulate cones are described from Pliocene sediments at Ch’ijee’s Bluff on the Porcupine River, near Old Crow, Yukon Territory, Canada. Cones are ovoid to conical, symmetrical, 3.4–4.4 cm long and 2.8–3.4 cm wide, with helically arranged cone-scale complexes....

A non-ideal osmotic equilibrium equation is proposed as a replacement for the Boyle van’t Hoff equation to describe the equilibrium volume of a living cell as a function of external osmolality. Contrary to common understanding, the Boyle van’t Hoff equation is only valid for ideal, dilute...

This study focuses on simultaneous vibration suppression and energy harvesting in a broad frequency band. For this purpose, a variant nonlinear energy sink (NES) is developed. The developed variant NES consists of a nonlinear oscillator and an electromagnetic energy harvester. Unlike a true NES,...
